RUDD HARDESTY, OF DENVER, COLORADO.

PERGOLATOR.

Specification of Letters Patent.

Patented July 27, 1909.

Application filed April 8, 1908. Serial No. 425,935.

To all whom it may concern:

. Be it known that I, RUDD HAnnEsTY, a citizen of the United States ofAmerica, residing at Denver, in the county of Denver and State ofColorado, have invented certain new and useful Improvements in Percolaetors, of which the following is a specification.

My invention relates to improvements in percolators and moreparticularly to the class of devices employed in the manufacture ofsyrups and its object is to expedite the process of producing saccharinesolution by providing an apparatus of the class named in L which thesolvent employed to dissolve the sugar filters through comparativelysmall quantities of the latter which are successively and automaticallysupplied from the mass with which one of the compartments included inthe contrivance, is filled.

Other objects of my invention will be brought out in the course of thefollowing description reference being had to the accompanying drawingsin the various views of which like parts are similarly designated and inwhich Figure 1- represents a central vertical section through thepercolator and- Fig. 2 a transverse section taken along a line 22, Fig.i.

The device as illustrated in the drawings is composed of threedetachably connected sections A, B and C, which when assembled onewithin the other, provide three compartments which, in the practice ofthe process for which the apparatus is designed, respectively containthe sugar, the solvent and the solution.

The lower section O of the device consists of a cylindrical receptacleprovided in proximity to its bottom, with a valveor gatecontrolledoutlet O through which the saccharine solution may be drawn and near itsupper extremity or rim withan inverted vent pipe 0 through which the airdisplaced by the rising fluid, may escape from the interior of thereceptacle.

The middle section B comprises a funnel a cylindrical top portion B ofwhich is adapted to sit upon the rim of the lower receptacle andterminates in a downwardly extending cone B which, in practice, projectswithin the receptacle O in spaced relation to its inner circumferentialand bottom surfaces and whose lower orifice is covered by a screen orforaminated plate B through which the solution formed in the middlecompartment, passes into the lower one.

The cylindrical portion of the member B is formed with an opening Bwhich being surrounded by an outwardly projecting lip B provides aninlet for the solvent with which, in practice, the middle section iscontinuously supplied. A lid B, hingedly connected with the lip B isadapted to close the 111- let so as to exclude dirt anddust from theinterior of the sections. I

The upper and innermost'section A of the" device is composed of acylindrical top portion A which when the parts are assembled, issupported upon the upper edge of the middle section and whose lowerextremity connects with a conoidal throat r which terminates into adownwardly extending spout A the orifice of whichextends a predetermineddistance above the foraminated bot tom plate B of the middle section.

In the operation of my improved percolator, the upper vessel A is filledwith sugar, a portion of which is discharged therefrom through the spoutA upon the foraminated bottom B of the middle section, the quantity ofthe saidportion being determined by the distance between the orifice ofthe spout and the plate B The water or other solvent which is introducedinto the middle compartment through the inlet B slowly percolates thequantity of sugar contained therein and carrying a portion thereof insolution, passes through the perforations in the plate B to collect inthe lower receptacle C, while the quantity of sugar which is diffusedinto the said solvent, is synchronously replaced by a similar qliaitltyfrom the mass contained in the vesse It will thus be observed that bythe use of my apparatus the process of producing the syrup is renderedcontinuous and greatly expedited by reason of the fact that the solvent,instead of passing through the entire mass of sugar with which the uppervessel is filled, is

brought in contact with but a small portion when the supply of syrupautomatically ceases until through the instrumentality of the outlet O,all or a portion of the fluid contained in the lower section, is drawntherefrom.

Having thus described my invention what I claim is 1. A device of thetype set forth composed of a lower receptacle, a middle receptaclecomposed of a top portion and a downwardly extending cone forming ashoulder supported by the top edge of said lower receptacle, said coneprojecting in the lower receptacle and having a perforated bottom spacedfrom the bottom of said lower receptacle, said middle receptacle havingan inlet in its top portion, and an upper receptacle havinga topportion, a conoidal throat and a downwardly extending spout whichextends into said cone of the middle receptacle and terminates at apoint above said perforated bottom of the middle receptacle, said topportion of the upper receptacle seating on the top portion of the middlereceptacle.

2. In a device of the type set forth, a solvent receiving receptaclehaving a perforated bottom, and a sugar receptacle having a spout formedwith imperforate sides and an open mouth, said spout being adapted toproject into the body of the solvent and discharging the sugar therefromat points above the bottom of the solvent receiving receptacle.

3. A device of the type set forth, composed of a syrup receivingreceptacle, a solvent receiving receptacle disposed above said firstreceptacle and communicating therewith, and means cooperating with thesolvent re- 7 ceiving receptacle to automatically feed but apredetermined amount of sugar to said solvent receiving receptacle tothereby come in contact with the solvent.

4. A device of the type set forth, composed of a syrup receivingreceptacle, a solvent receiving receptacle projecting partly into saidfirst receptacle and having a ioraminous bottom, a sugar receivingreceptacle provided with an imperforate spout having a contracted mouthprojecting into said solvent receptacle, the distance between said mouthand said foraminous bottom of the solvent receptacle determining themaximum amount of sugar automatically fed into said solvent receptacleso as to come in contact with the solvent.

5. A device 01' the type set forth, composed of a solvent receivingreceptacle having a perforated bottom, and a sugar receptacle providedwith an open discharge mouth having imperforate side walls spaced fromthe bottom and side walls of said solvent receptacle whereby but apredetermined quantity of sugar is automatically fed into said solventreceptacle to come in contact with the sol vent.

6. A device for the manufacture of syrup, embodying a solvent receivingreceptacle having a perforated bottom, a sugar receptacle, and meansconnected to said sugar receptacle and projecting into the body of thesolvent to discharge the sugar at points above the bottom of saidsolvent receptacle whereby but a predetermined quantity of the sugarcomes in contact with the solvent.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
